[Difficulty experienced by family in supporting elderly diabetic patients is associated with a decline in patients'...

To examine the relationship between difficulties experienced by family in supporting elderly patients with diabetes and these patients' higher-level functions.

The subjects were outpatients with diabetes ≥65 years old at Ise Red Cross Hospital and their family members. The Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) was used to assess patients' higher-level functions. The Japanese version of the Diabetes Caregiver Activity and Support Scale (D-CASS-J) was used to measure difficulties experienced by family in supporting elderly patients with diabetes. Using a multiple regression analysis with TMIG-IC scores (instrumental ADL, intellectual activity, and social participation) as the dependent variable and D-CASS-J scores (based on the highest scoring Q1 group among the three quartiles of D-CASS-J scores) as the explanatory variables, standardized regression coefficients (β) for higher-level functions on the family's perceived support difficulties were calculated.

In total, 429 patients (254 male patients and 175 female patients) were included in the analysis. For male patients, the adjusted beta values for TMIG-IC scores in Q2 and Q3 were -0.039 (P=0.649) and -0.352 (P<0.001), respectively, and the adjusted beta values for the instrumental ADL scores were -0.064 (P=0.455), -0.192 (P=0.047), -0.090 (P=0.375), and -0.360 (P=0.002) for the Intellectually Active scores, respectively, and the adjusted beta for social role scores were 0.054 (P=0.581) and -0.261 (P=0.019), respectively. However, there was no association between the patients' higher-level functions and family support difficulties among female patients.

Difficulty experienced by the family in supporting elderly male patients with diabetes is associated with reduced higher-level functioning.
